CONTROLS

A. GEAR SHIFT AND THROTTLE CONTROL

The shift/throttle control unit for the engine activates

by the shifting mechanism and the throttle (Figure

2.8.2). The control must be in neutral position to start

your engine. Moving the lever forward first engages

the forward gear. Further forward movement

increases engine speed and propeller RPM, moving

the boat faster. To shift to reverse, bring the control

lever back to the neutral position, then move it

further back to engage the reverse gear. Further

rearward movement of the lever increases engine

speed and propeller RPM, moving the boat faster

in reverse.

Shift/throttle controls are equipped with a “throttle

only” mechanism which allows the shift mechanism

to be disengaged from the throttle. This allows the

throttle to be advanced without shifting the

transmission when starting. It may be necessary to

use the “throttle only” button in order to pump fuel

into the engine for ease in starting.

The “Throttle Only” mechanism (Figure 2.8.2) may

differ from one style gear/throttle unit to another.

Refer to your Gear Shift & Throttle Manual for proper

operation of this feature.

The throttle control adjusts the RPM of the engine

and thus, the rotational speed of the propeller.

Regulating the RPM of the engine controls the

speed of the boat.

Forward motion creates forward moving water

called a “following” wake. If the boat is moving

forward and the shift/throttle is moved quickly from

forward to reverse, the boat will stop rapidly and

then move backward. The following wake continues
